The systematic X-ray absorption near edge structure (XANES) investigation at Au L3-edge was made on Au in metallic form and its compounds in various definite oxidation states, viz., Au(OH)3, AuCl, AuCl3, HAuCl4, AuI and AuBr3. The spectra have been r

Experiments by F. Zhou and coworkers (2010) [16] showed that mitochondria are the main target of the cellular accumulation of single-walled carbon nanotubes (SWCNTs). Our in silico experiments, based on geometrical optimization of the system consisti
